In September 2019, the U.S. Consumer Product Safety Commission (CPSC) published an update to the consumer product safety standard for infant bath seats under the Consumer Product Safety Improvement Act of 2008 (CPSIA). The standard incorporated by reference ASTM F1967-19, Standard Consumer Safety Specification for Infant Bath Seats, the voluntary standard for infant bath seats that was in effect at the time. ASTM has now issued a revised standard, ASTM F1967-24. The CPSIA sets forth a process for updating mandatory standards for durable infant or toddler products that are based on a voluntary standard, when a voluntary standards organization revises the standard. Consistent with the CPSIA update process, this direct final rule updates the mandatory standard to incorporate by reference ASTM's 2024 version of the voluntary standard.
